Replacement NinjaKid2 MC8123 eprom

Instructions

- Remove the metal encased MC8123 cpu and replace with a Z80B. A Z80A may work, but the pcb will run it at 5mhz, and the Z80A is only rated for up to 4mhz.
- Program a 27c512 with the replacement code and replace eprom 06 at 3h with it. (or erase the original)

Enjoy
